Ohio Electrical Contractor License: Exam Requirements, NEC Edition & Fees (2026)

Ohio doesn't license individual journeyman or master electricians at the state level — the Ohio Construction Industry Licensing Board (OCILB) only licenses Electrical Contractors. If you're an employee working under a licensed contractor, the state has no exam for you at all; that's handled locally. Here's exactly how OCILB's contractor exam works, straight from the PSI Candidate Information Bulletin.

Quick Answer

Who Regulates Electrical Work in Ohio

The Ohio Construction Industry Licensing Board (OCILB), under the Department of Commerce's Division of Industrial Compliance, determines eligibility and licenses Electrical Contractors statewide. OCILB has contracted with PSI Services, LLC to develop and administer the actual exams at computer testing centers across Ohio (Akron, Cambridge, Cincinnati/Hamilton, Cleveland, Columbus North and South, Macedonia, Maumee/Toledo, Troy, and Wadsworth, among others).

Why There's No Individual Electrician License

Ohio's state-level licensing structure mirrors what we've seen in states like Mississippi, Missouri, and New Jersey: OCILB licenses the business — the Electrical Contractor — not individual tradespeople working underneath one. There is no statewide journeyman or master electrician exam or credential in Ohio. If you work as an employee electrician under a licensed contractor, the state doesn't require you to hold a personal license at all; local jurisdictions may have their own separate rules (see below).

Eligibility

To qualify for the Electrical Contractor exam, you need at least five consecutive years of experience in the electrical trade, or you can qualify as a registered Professional Engineer in Ohio with three years of construction business experience. You must submit a notarized application to OCILB along with the appropriate fees, and once approved, you're required to pass a state and federal background check before you're eligible to sit for the exam. OCILB approval to test is valid for one year — if you haven't completed your background check and taken the exam within that window, you'll need to reapply. Licensed contractors must also carry general liability insurance of at least $500,000.

Two Exams: Electrical Trade and Business & Law

Per the PSI bulletin: "All applicants for contractor commercial licenses must take the Ohio Contractor's Business and Law exam in addition to any required trade-specific examination." Both are required for a first-time Electrical Contractor license.

If you later decide to license in a different Ohio contractor trade, you only need to pass the Business and Law exam once every three years — you don't retake it for every additional trade license within that window. Electrical trade-exam content covers general electrical knowledge, transformers and equipment, services/feeders/branch circuits, raceways/boxes/panelboards, conductors and cables, control devices, motors and generators, utilization equipment, and special occupancies and equipment.

NEC Edition and Reference Rules

Ohio's Electrical Contractor exam is confirmed open book, and the current PSI bulletin lists the exact allowed references: "Ugly's Electrical References, 2023" and "NFPA 70 – National Electrical Code, and/or The National Electrical Code Handbook, 2023" — either reference alone is sufficient, and you may bring both. An older Electrical Field Reference Handbook (revised for NEC 2008) or the IBEW-NECA Field Reference Book are also listed as acceptable. You bring your own copies, and per the bulletin: "Reference materials may be highlighted, underlined, and/or indexed prior to the examination session. However, references may not be written in" during the test itself, and no loose or attached extra papers are allowed with your references.

The Business and Law exam works differently — it's open book, but the reference (the NASCLA Contractor's Guide to Business, Law, and Project Management – Ohio, 4th Edition) is provided at the testing center, and the bulletin is explicit: "No highlighting or notes of any sort may be made in the book during the exam." You don't bring your own copy for this one.

Fees

Per the PSI bulletin, the examination fee is $69 per registration — that's for each exam, whether it's your first attempt or a retake, and it's non-refundable and non-transferable. This is separate from OCILB's own application fee (commonly cited as around $25) and any license-issuance fees charged directly by the board — confirm current OCILB application and license fees on their own site, since the PSI bulletin only covers the testing fee.

Retesting

• You have one year from OCILB's eligibility notification to schedule and take your exam, or your eligibility expires and you must reapply.
• If you fail an exam portion, you must wait 60 days before retesting.
• You may retest up to 5 times in a year.
• Cancel or reschedule at least 2 days before your appointment or you'll forfeit your fee.

A Note on Local City Licensing

Because Ohio's state license covers only the contractor level, individual cities may impose their own separate licensing or registration requirements for electricians working within their limits. We have not independently verified specific local requirements for Ohio cities such as Columbus, Cincinnati, or Cleveland — if you work as an individual electrician (not a licensed contractor) in a specific city, check with that city's building department directly.

Frequently Asked Questions

Does Ohio have a journeyman or master electrician license?

No, not at the state level. OCILB only licenses Electrical Contractors. Individual electricians working under a licensed contractor aren't required to hold a state license, though local cities may have their own separate rules.

What NEC edition does Ohio's electrical contractor exam test?

The 2023 NEC (NFPA 70), per the current PSI Candidate Information Bulletin, which also lists the 2023 edition of Ugly's Electrical References as an allowed companion resource.

Is the Ohio electrical contractor exam open book?

Yes, and you bring your own reference materials, pre-highlighted, underlined, or indexed before the exam. This is different from the Business and Law exam, where the reference book is supplied by the testing center and cannot be marked at all.

Do I have to retake the Business and Law exam for every trade license?

No. Per OCILB/PSI, once you've passed it, you only need to retake the Business and Law exam once every three years, even if you later add licenses in other contractor trades.

How much does the Ohio electrical contractor exam cost?

$69 per exam registration (per the PSI bulletin), for each exam and each attempt, non-refundable. This doesn't include OCILB's separate application and license-issuance fees.

Study Materials

This is a case where we can recommend with confidence: Ohio's own PSI bulletin lists the 2023 NEC (NFPA 70) and 2023 Ugly's Electrical References as allowed exam-room materials, and permits candidates to highlight, underline, and tab their own copy before test day. Our 2023 NEC Handbook Bundle with Tabs and free Ugly's Electrical Reference matches this exam's requirements directly — just don't do any writing in the book once you're in the exam room, and remove any temporary sticky-note tabs before you sit down, since only permanent markings applied beforehand are described as acceptable.
